The present invention relates to an ultraviolet and infrared absorptive greenish glass (the first glass) containing in weight % expression at least coloring components of 0.3-0.5% of total Fe 2 O 3 , 0.8-2.0% CeO 2 , 0.8-2.0% TiO 2 , and 0.10-0.25% of FeO. This first glass may be an ultraviolet and infrared absorptive greenish glass (the second glass) in which CeO 2 amounts to 0.8-1.5% and TiO 2 amounts to 0.8-1.5%, and which contains at least 0.1-0.7% SnO as a coloring component. Each glass is characterized in each glass at 5mm thickness is 9% or less in ultraviolet transmittance (T uv ) according to ISO/DIS9050, 1% or less in 350nm wavelength transmittance (T 350 ), 70% or greater in 550nm wavelength transmittance (T 550 ), and 25% or less in 1100nm wavelength transmittance (T 1100 ). |
